this squeelings gut to go

[uchy1991]

I have a 91 mtx and basically when ever i drive there is this non stop imbarising squeeling. Its not too loud but the faster i go the faster it squeels ...Also i jacked up both tires and hand spun them myself so i know its not my breaks.. please let me know if you can help me out... Thanks

Does it squeal in neutral? Like when you rev the engine and you're not moving? If it does, remove the belts. If the squealing stops, it was your belt (or a pulley). Tighten or replace as necessary. Spin all the pullies by hand while the belts are off to see if any of them are squealing.

If it doesn't squeal when you're not moving, it could be a wheel bearing. While the car is jacked up, grasp a wheel (it needs to be on to get enough leverage) by the 12 and 6 o'clock positions and try to wiggle it. If it wiggles, even a little, the wheel bearing is bad and needs replacing pronto. (wiggle in the tire with hands at 3 and 9 o'clock indicates bad tie rod ends)

If it's not that, then it could be the CV axle, but those don't normally squeal, they thunk.

So try testing the wheel bearings out and let us know the results.

Agreed with hawkeye18, if it does it while it is idling and driving it is probably either a belt or a bearing on one of the accessories (ie. water pump, a/c compressor, etc. anything on the left side of the engine driven by a belt.) Replaced the water pump on mine a couple months ago for this reason. If it helps, while idling, try taking a large screwdriver and pressing it against different accessories and listen to the other end. This will help to identify which one is causing it if it sounds like it is coming from that part of the engine.
(this is all assuming it makes noise while idling)
